A synthesis of the beta-lactone esterase inhibitors (-)-ebelactones A and B is described. The synthesis features the use of a Hoppe homoaldol reaction and a Cu(I)-mediated 1,2-metallate rearrangement of a metallated enol carbamate as key fragment linkage reactions. (C) 2010 Elsevier Ltd.

The present invention relates to the chemical synthesis of vittatalactone, the aggregation pheromone of the striped cucumber beetle,
Acalymma vittatum.
The present invention relates to specific beta-lactone compounds and compositions thereof for the treatment of infections, such as, e.g., infections with bacteria or infections with protozoa, in particular infections with Gram-positive and/or Gram-negative bacteria and of infectious diseases caused by or related to Gram-positive and/or Gram-negative bacteria, and to the modulation of virulence of Gram-positive and/or Gram-negative bacteria or of protozoa by specific beta-lactone compounds. The invention further relates to the use of the compounds or compositions for preventing or eliminating biofilms.
The present invention is directed to materials containing an enzyme inhibitor, including treated fibers, nonwovens, functional particles and processes for making these materials. These materials are useful in reducing or delaying onset of odor generation from various waste materials including human and animal elimination products.

An absorbent article, at least a portion of which comprises a skin care composition that comprises an enzyme inhibitor and is at least partially transferred from the article to the skin of a wearer of the article as a result of normal contact, wearer motion and/or body heat. The enzyme inhibitor is transferred to the skin with the skin care composition and is available at the skin/urine and skin/feces interfaces to inhibit enzymatic activity on the skin and to reduce or prevent the occurrence of inflammation. Repeated application of similar treated articles to the wearer's skin provides an available source with which the enzyme inhibitor transfers onto the skin continuously over time and accumulates to provide a proactive defense against harmful enzymes for the treatment and/or prevention of diaper dermatitis.
